抜粋

Previously, beam bending tests had been conducted on strengthened RC beams with polyurea resin layer, which has low elastic modulus and high elongation, between the CFRP strand sheet (strand sheet for short) and concrete surface. It was found out that polyurea resin layer improves the bonding ability between the strand sheet and concrete surface. In this study, in order to examine the bonding ability of strand sheets with polyurea resin layer, a series of bonding test was carried out. Especially to verify the applicability of this method at elevated temperature for structure such as a chimney, bonding test at different temperature were selected. As a result, it was found out that bonding strength with polyurea resin was about 2.8 times more than that without polyurea resin at room temperature. Furthermore, it was found out that sufficient bonding performance can be achieved even at high temperature.
